Title:
DATA TRANSMISSION METHOD, APPARATUS AND DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/203253
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data transmission method, apparatus and device, and a computer readable storage medium. The method comprises: sending a channel occupancy indication before the start of uplink transmission, the channel occupancy indication being used for instructing a neighboring node of a base station not to send data; and receiving uplink data sent by a User Equipment (UE). The method achieves that: the base station sends a channel occupancy indication before the transmission of the uplink data of the UE starts so as to instruct the neighboring node of the base station to back off, i.e., instruct the neighboring node of the base station not to send data, and the UE is instructed to transmit uplink data, so that after occupying a channel, the UE does not need to send a channel occupancy indication to the base station, and the UE can directly start the transmission of uplink data, thus the problem of interference of hidden nodes is solved, and transmission resources can be saved.
